The tank contained pond water (PH ? 7.2, oxygen? 4.3 mg/l, temperature? 26. 2 ⁰C). The fish were fed at 3% of body weight twice a day between 8.00-9.00 am and 4.00-5.00 pm for a period of 90 days.

Dietary Fluted Pumpkin (Telfairia occidentalis) Improves Reproductive Indices in Male African Catfish (Clarias gariepinus) Broodstock

“…Dada (2013) reported that catfish C. gariepinus broodstocks fed on diets supplemented by medicinal plants exhibited improved reproductive performance than those fed with the control diet. Similar results were reported for using medicinal plants as fertility-promoting agents for catfish C. gariepinus (Dada & Ajilore, 2009;Adeparusi et al, 2010;Dada & Ogunduyile, 2011 Vol. 7, No.…”

The effects of Brazilian tea (Stachytarpheta jamaicensis) and Bitter kola (Garcinia kola) seed meal on the growth and gonad development of the African catfish Clarias gariepinus (Burchell, 1822)

“…Fecundity was high in all treatments, although fish fed to control diet exhibited the highest fecundity (11,834 ± 1643.93). Fecundity of fish fed to the control diet was significantly higher than fecundity of fish fed to diet B and diet C. Adeparusi et al (2010) also reported similar findings on the use of medicinal plants for catfish C. gariepinus. Histology of ovaries and testes of fish fed to the three experimental diets in this study showed normal distribution of oocytes and testicular cells.…”

Application of phytochemicals as growth‐promoters and endocrine modulators in fish culture

“…Dietary supplementation (1%) of lowbush blueberry, Vaccinium angustifolium, product that contains high phenolic content including the flavonoids anthocyanins, was found to inhibit lipid peroxidation in Arctic char, Salvelinus alpinus, semen by decreasing the rate of sperm lipid peroxidation and increasing the antioxidant potential of seminal plasma (Mansour et al 2006). Adeparusi et al (2010) investigated the effects of Kigelia africana fruit on sperm quality of C. gariepinus. Fish were fed diets containing K. africana root powder at concentrations of either 50, 100, 150 or 200 g kg À1 diet for a period of 90 days and milt qualities were assessed by microscopic studies and fertility tests.…”
